Pigment Diagnostics: Large scalloped pigmented pectoral fins, distinguished from
Nautichthys oculofasciatus by: body pigment does not extend onto dorsal- and anal-finfolds during preflexion and flexion stages
Diagnostics: Deep-bodied, short and stocky compared with
Xeneretmus latifrons; body spines develop in flexion larvae; distinguished from all NE Pacific agonids by: scalloped pectoral fins and low vertebral count; distinguished from
Hypsagonus spp. and
Percis japonicus by: less pigmentation and a longer predorsal length; distinguished from
Nautichthys oculofasciatus by: lower vertebral, dorsal-fin ray, and anal-fin ray counts
